Praxis 5511 Practice Question
The Sun transfers heat to Earth by
Correct Answer: B
Rationale: The Sun transfers heat to Earth primarily through radiation, which involves the emission of energy in the form of electromagnetic waves. This process allows heat to travel through the vacuum of space, reaching our planet.
Conduction (Option A) requires direct contact between materials, which does not occur between the Sun and Earth. Ionization (Option C) refers to the process of removing electrons from atoms, not a method of heat transfer. Sublimation (Option D) is the transition of a substance from solid to gas, unrelated to how the Sun heats Earth. Thus, radiation is the only relevant mechanism for this energy transfer.
